A country school where children play in the mud and climb trees is under threat of having its teaching resources halved.

Since the start of the year the Kereru School roll has dropped from the “magic number” of 26 students to 22, which means funding for two full-time teachers and a relief teacher three days a week will no longer be in place from the first term next year.

Instead there will be funding for one full-time teacher and a relief teacher for one and a half days a week and two classrooms will turn into one.

Three sisters who were at the school between 1983 and 1997 and now have their own children at the school are pleading for more families to enrol their children.

The oldest sister, Amy Dunn, said three or four families had moved out of the area recently, which affected the school roll.

“We are a small community ,so you can imagine the impact that has on our school.”

Ms Dunn said with the number of teachers dropping they would have to go down to one classroom, which with students ranging in age from 5 to 12 was not ideal.

The school, which is more than 100 years old, has a junior and senior classroom, with principal Chris Birch and Jade Lanauze teaching, as well as a relief teacher.

“They are small class sizes so the kids get so much help and individual attention, it has all been going really well and I can see the difference in my own children.”

The three sisters, Ms Dunn, Emily Hunter and Laura Grady, will make up a quarter of the school role next year when Elsie Dunn, four, joins her brothers and cousins.

Ms Hunter said they would not send their family anywhere else and some of the traditions they had when they were there were still going strong.

“I can remember the Christmas concert back in our day; there are so many good memories and it’s such a unique and special place for kids to grow up.”

The school already does a lot of fundraising for everyday upkeep and to fund a teacher as well would be near impossible.

Ms Grady said she did not think they could bake quite enough cakes to keep a teacher on.

Mr Birch said being staffed like a large town school wasn’t practical but as soon as the roll was back up to 26 they could claim back their teaching resources.
